My bike came with a flat non sealed beam headlight marked "Aprilia". I just bought one of the headlights on eBay from the Netherlands, which Giovanni says are American headlights. It came with a sealed beam light. Did American bikes come with both types of headlight, or is my original one ...

I've just recovered my seat. When I took off the old cover, the front end was secured to the seatframe by 3 barbs in the seat frame - I assume I'll do that again. But the back was held down by a lot of silicone sealant - which did a good job of rusting the metal. How were they done originally, and w...

Yep - I realized that regular black pipe from the plumbers supply is about 1" ID and just fits. I just stuck a piece in the lathe and trued one end. The outer races look simple - I assume that if I stick them in the freezer and heat the frame gently I can tap them into place pretty easily. Any ...

When you replace the lower headset bearing, how do you seat it? Do you fabricate a tool that's a pipe with the proper ID to drive the bearing evenly?

Thanks - Peter Tourin

Thanks - I emailed Atmus to see if they have them in stock. My local shop couldn't even ID the number - told me it was bad. We'll see if Boston can do better....

Thanks again - Peter

That's more or less the way I see it -- I can't imagine that it'll do anything that I'll notice -- as long as it doesn't make things WORSE <bg>....

I'm rebuilding a 750GT that I picked up in December. It's got a 2nd plug in each head, on the opposite side from the original plug. The man who sold me the bike wasn't the one who had the 2nd plug installed, and couldn't tell me anything about it. Can anyone tell me anything about twin plug conversi...

I'm not having much luck locating headset bearings. I took the number from this forum - SKF-639174 - to our local bearings supply house and they say it's a bad number. I did an internet search and found another number - SKF-235321 - and my supplier says that this is also a bad number. Can anybody gi...

If it's a press fit, does the washer that comes with the kit go under the rubber and metal rings, as in the parts manual? When I disassembled, I didn't have one, so I want to make sure before I reassemble.

Thanks - Peter

I've got an assembly question about the 15 mm front brake master cylinder rebuild kit. On the piston end nearest the lever, there's a washer and a rubber ring surrounded by a metal ring. They're supposed to stay down in the bore, but as the piston moves, they ride out towards the brake lever and fin...

I'll check my gun and see if it likes vintage Italian brakes....

Thanks, good to know. I'll start pounding the caliper I didn't heat first, and see how it goes. - Pete

> Hopefully you didn;t melt the rubber and kill your caliper.............. < Well, tell me I haven't trashed anything yet.... The only rubber I see is an o-ring between the caliper halves and the seal on each side around the piston. The seals are very old and dirty, and I pulled them before doing an...

Can anyone give me some helpful hints for freeing up frozen calipers? I soaked my 2 calipers with PB Blaster for a week, clamped a rubber hose to the brake line and hit them with 120 PSI -- no luck. I heated the outside of one caliper with a torch to see if I could heat shock the piston loose -- aga...

Hi Steve - I'll keep the dual disks - I also agree they look cool. I'm just starting to look the bike over - picked it up just a few days ago. It's suffered a lot of neglect and will take lots of cleanup. Is there any table of bike production info? VIN is DM750S755587, and I'd like to find out whate...
